These OEM replacement carbon brushes are sold as a pair and include a coiled spring attached. These brush and spring assemblies are what deliver power to a rotary tool armature. The spring transfers power and helps to secure the brush tightly in place. These brushes are in constant contact with the armature, which causes them to wear over time, and is the reason you should also inspect the armature regularly as well. If the tool is overloaded this can also cause the springs to burn. When performing this repair, be careful not to over-tighten the brush caps because they can crack.
